Answer:
- see the attachment
- (x, y) = (1, 1)
Step-by-step explanation:
1. Since you have y > ..., the boundary line is dashed and the shading is above it (for y-values greater than the values on the line). The boundary line is ...
y = 2x+3
which has a y-intercept of 3 and a slope (rise/run) of 2. A graph is attached.

2. You can add the two equations to eliminate y:
(3x +y) +(x -y) = (4) +(0)
4x = 4
x = 1
1 - y = 0 . . . . substitute into the the second equation
1 = y . . . . . . . add y
The solution is (x, y) = (1, 1).

Answer: 135
Step-by-step explanation:
Find the difference between the members. The difference between every two adjacent members of the series is constant and equal to 4. The sum of thUsing our example, consider the sum. This sum can be found quickly by taking the number of terms being added (here 5), multiplying by the sum of the first and last number in the progression (here 19 + 35 = 54), and The sum of the 5 members of this series is 135 dividi This series corresponds to the following straight line y=4x+19ng by 2. Of a finite arithmetic progression is called an arithmetic series.
